To all whom t may concern:

Be it known that I, HARRY J. FRANK, a citizen of the United States,residing atPhiladelphia, in the county lof Philadelphia and haveinvented new and useful Improvements in Dumping-Wagons, of which thefollowing is a specification.

My invention relates to dumping-wagons, and has for its primary objectto provide an improved means for lifting the wagon-body to the dumpingposition and for causing said wagon-body to assume any one of severaldumping positions in order that the same may be adapted for use underall circumstances.

A further object of my invention is to so arrange the lifting mechanismbeneath the wagon-body that the same when inactive will be positionedsome distance above the ground, whereby danger of its being struck andbroken when the wagon is passing over rough ground will be obviated.This object I accomplish in the manner and by the means hereinafterdescribed and claimed, reference being had to the accompanying drawings,in which- Figure 1 is a side elevation, partly broken away, ofsufficient of a coal-wagon to illustrate my improvements, the wagon-bodybeing shown in its lowermost position. Fig. 2 is` a similar view showingthe wagon-body partly raised, the parts being in position to raise it tothe highest dumping position. Fig. 3 is a similar view showing thewagon-body raised to substantially the highest dumping position. Fig. 4is a similar view showing the wagon-body with its rear end resting onthe sills for a short steep dump.

Similar numerals of reference denote corresponding parts in the severalviews.

In the said drawings the reference-numeral 1 denotes the wagon-body, and2 the sills forming part of the frame. Suitably mounted on said frame isthe usual transverse operating-shaft 3, to which rotation is imparted bymeans of gearing 4 and operating-handle 5. Pivoted to the body 1 at 6 oneach side of the wagon-body is a bell-crank lever the long arm 7 ofwhich is curved slightly to the rear at its lower free end and which isformed with respect to its short arm 8 at an angle slightly less than aright angle, as shown. Also pivoted to the body 1 at 6 on each side is astrai ht arm 9, running rearward therefrom an pivoted at its other endat 10 to the sill 2. Pivoted to the sill 2 on each side at 11 is acurved arm 12, having its lower free end pivoted to the lower end of arm7 ofthe bell-crank lever, while attached to said lower end of arm 7 is acord or chain 13, the same being attached at its other end to shaft 3and adapted to be wound thereon. Projecting downwardly from the underside of the body 1 on each side thereof and adjacent the free ends ofthe arms 8 is an arm 14 for a purpose hereinafter to be described.

From the above description the operation of my improved constructionwill be understood to be as follows: With the body 1 in the positionshown in Fig. 1, and it being understood that the pivot-point 6 islocated slightly to the rear of the center of gravity of body 1, anupward movement of the bellcrank levers imparted through windingchains13 on shaft 3 by means of crank-arm 5 and gearing 4 will first raise therear end of body 1 until it reaches the position shown in Fig. 2, thestraight arms 9 acting as guides for the body 6, while curved arms 12act as guides for the lower ends of the bell-crank levers. When thisposition is reached, however, the short arms 8 of the bell-crank leverswill come in contact throughout their length with the under side of thewagon-body 1, as

shown in Fig. 2, the result being that during the further liftingoperation the wagon-body 1 must be in the same plane with the short arms8 of the bell-crank levers, and said body will thus be gradually tiltedto the rear until it reaches the position shown in Fig. 3, which is theposition for distance-dumping. When it is desired to shorten the dumpand at the same time to increase the inclination of the wagon-body, Iaccomplish the same in the following manner: rI`he short arms 8 of thebell-crank levers are apertured at their outer ends to register with anyone of a series of similar apertures 15 in the arms 14. Now when thewagon-body is in its lowermost position (shown in Fig. 1) the aperturesin arms 8 will register with the lowermost of the series of apertures 15in arms 14, when by slipping pins 16 thereinto the two arms will befirmly united, so that when the long arms 7 are raised by winding upchainsv 13 on shaft 3 the body 1 being connected to the said bellcranklevers at two points will be raised bodily thereby on its rear end as apivot until it reaches the position shown in Fig. 4, thus giving a shortsteep dump. By providing the series of holes 14 in the arms 15 the angleof inclination of the wagon-body may be va- IOO IOS

ried, for by rst raisin arms 7 and body 1 from its rear until the olesin short arms 8 register with the second holes 15 from the bottom ofarms 14 and then inserting the pins 16 the result will be that when arms7 are fully raised the body 1 will be in a position in respect to itsangle of inclination intermediate those shown in Figs. 3 and 4, thoughnecessarily nearer that shown in Fig. 4. So, also, by postponing theinsertion of pins 16 until the uppermost of the series of holes 15 isreached the ultimate angle of inclination of the body 1 will belessened, though still greater than that shown in Fig. 3.

By referring to Fig. 1 it will be observed that by reason of the curvingof arms 12 and the lower ends of arms 7 the lower connected ends of thesame are brought forward horizontally beneath the rear axle of thewagon, and thus well lifted from the ground, in practice leaving aclearance of about fourteen inches, thus reducing to a minimum thedanger of said arms striking an underlying object while traveling overrough ground.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is`- 1. In a dumping-wagon, the combinationwith the frame, and the wagon-body, of a common means for lifting saidbody from said frame and for simultaneously tilting said body to apredetermined angle of inclination during its upward movement.

2. In a dumping-wagon, the combination with the frame, and thewagon-body, of a pair of levers for lifting said body having a fixedpoint of connection therewith and also a variable point of connectiontherewith, whereby the ultimate angle of inclination of said body may bevaried.

3. In a dumping-wagon, the combination with the frame, and thewagon-body, of a pair of bell-crank levers for lifting said body havinga fixed point of connection therewith at the intersection of the twoarms composing the same, and means for variably connecting one pair ofarms of said bell-crank levers with said body, whereby the ultimateangle of inclination of said body may be determined.

4. In a dumping-wagon, the combination with the frame, and thewagon-body, of a pair of bell-crank levers for lifting said body andpivoted thereto at the intersection of the two arms comprising the same,said pivotpoints being to the rear of the longitudinal center of saidbody, one arm of each of said levers extending rearward of saidpivot-point and adapted to have the lifting power applied thereto, theother arm extending forwardly and adapted to be variably connected tosaid body forward of the longitudinal center of the same, whereby saidbody, when lifted, will assume a, predetermined but variable -angle ofinclination to the rear.

5. In a dumping-wagon, the comlbination with the frame, and thewagon-body, of a pair of bell-crank levers for lifting said body andpivoted thereto at the intersection lf'the two arms comprising the same,said pivotpoints being to the rear of the longitudinal jcenter of saidbody, one arm of each of said levers extending rearward of saidpivot-point and adapted to have the lifting power applied ,thereto whilethe other arm extends forwardly therefrom, and an arm or arms exjtending downwardly from said body in proximity to the free end of one orboth of said variably connected therewith, whereby said ibody, whenlifted, will assume a predetermined but variable angle of inclination tothe rear.

6. In a dumping-wagon, the combination ;with the frame, and thewagon-body, of a p pair of bell-crank levers pivoted to said body `forlifting the same, means for causing said l body to assume apredetermined angle to the 1Irear when lifted, and levers pivoted tosaid ,frame to the rear and to said body at the i pivot-points of saidbell-crank levers for guidi ing said body with respect to said framedur- A ing its lifting and returning movement.

7. In a dumping-wagon, the combination with the'frame,l and thewagon-body, of a pair of bell-crank levers pivoted to the body forlifting the same, each having andownwardly-extending arm to which thelifting power is applied, and an arm for each lever pivoted at one endto the frame and at its other end to the end of said bell-crank-leverarm for guiding the latter in its movement.

8. In a dumping-wagon, the combination with the frame, and thewagon-body, of a pair of bell-crank levers pivoted to the body forlifting the same, each having a downwardly and rearwardly extending armto which the lifting power is applied, said arm being curved upwardly atits lower end, and a curved arm for each lever pivoted at one end to theframe and at its other end to the end of its said bell-crank-lever arm,whereby the latter is guided in its movement to the inactive position toa position wherein its lower curved end is substantially horizontal andraised from the ground.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
